Event image best practices

What makes a good event image?

Images should reflect the topic or give an overall sense of who, where and/or what the event is.

  • Correct pixel dimension: 600px x 600px
  • Include no text
  • High contrast ratio of at least 3:1 
    • The contrast between background and foreground should pass "Color Margins" based on the contrast checker 
  • Crisp and clear images -- not blurry, pixelated, skewed or stretched
  • Images need to be optimized (file size reduced for the web for fast load time).
    • File size: less than 50 kb
